- The object of my invention is to provide pasteboard blanks for makingboxes with angle binding-strips in such a manner that said strips arenot torn or ruptured when bending the blank to form the box.

The invention consists in grooving the pasteboard blank on the outside,then pasting the sideparts of longitudinally crimped or groovedbinding-strips on the blank at the sides of the grooves, the blank beingfiat while the said strips are being pasted on.

In the accompanying drawings, Figure 1 is a rear elevation of a machineused for pasting the edge and angle strips on the blanks for pasteboardboxes. Fig. 2 is a plan view of the same, the reels being omitted. Fig.3 is a cross-sectional view on the line as a, Fig. 1. Fig. 4 is anenlarged cross-sectional view of a pasteboard blank that has beencreased and grooved and 'upon which a strip has been pasted. .Fig. 5 isa cross-sectional view of the same bent at right angles. Fig. 6 is anenlarged horizontal sectional View of the pressing-roller used forgrooving the strip longitudinally. Fig. 7 is a plan view of a blank uponwhich the strips have been pasted at the edges and creases. I

Similar letters of reference indicate corresponding parts. 7

The feed-roller WV is journaled horizontally along the front edge of thetable A, upon which the blanks can be placed. On a rail B a series ofholders 0 are held vertically adjustable by bolts passed throughvertical slotsin the holders, the bolts being provided at their innerends with dovetailed heads, which can slide in a dovetailed groove ofthe rail B, nuts being screwed on the outer ends of said bolts. In thelower forked ends of said holders the pressing-rollers a are mounted,and at each side of each roller a disk 6 is mounted loosely upon theshaft of the roller a, and said disks are pressed against the sides ofthe roller a by springs d, surrounding the shaft of the roller andinterposed between washers b at the sides of the disks and the innersides of the shanks of the forked ends of the holders.

The apertures in the centers of the disk e are considerably larger thanthe diameter of the shaft, so that said disks can assume positionseccentrical to the shaft and roller a. On the upper end of each holder 0a reel or pulley c is mounted, from which a strip of paper or othermaterial passes to the corresponding presser-roller a and between thecorresponding disks 6, said strip also passing over the edge of a rollerg, which is moistened or provided with gum or paste, so that the stripis rendered adhesive before being pressed upon the blank. Adjacent tothe holders 0 the laterally-adjustable holders D are held on the rail B,and on said holders D the presser-rollers b are journaled. On the tableA the horizontal slides i are mounted to slide laterally, and areprovided with suitable clamping or looking devices a" for locking themin place and with the inclined guide-ribs i on the inner sides. On saidslides are mounted the horizontal or nearly horizontalcircumferentially-grooved .presser-rollers h, the moistening or gummingrollers l, and the reels or pulleys k. The edges of the slides i alsoserve as guides for the pasteboard blanks.

In case the pasteboard is rather thick and .is provided with grooves 01in its outer face where it is to be bent, the strips 7', that have beenpasted on, would be torn by bending the blank, and to avoid this I pastethe strip on in the manner shown in' Figs. 1 and 5-that is, in such amanner as to form a hollow ridge W over the groove a. When the blank isthen bent at right angles, as shown in Fig. 5, those parts of the stripthat are not pasted on-that is, the parts forming the hollow ridge-restfirmly on the outer sides of the pasteboard.

To paste the strips on so that they form the hollow ridge, I provide thepresser-roller (I with a circumferential groove and mount acomparatively sharp-edged roller on adjacent to the grooved roller a,the edge of said roller m pressing the longitudinal central part of thepaper or other strip into the circumferential groove of thepresser-roller a.

The operation is as follows: The blank of pasteboard, which has beenpreviously creased on the inside or creased on the inside and grooved onthe outside on the lines on which it is to be bent to form the box, isplaced upon the table A and is moved in the direction of the arrow 0c,the slides or guides 1' being so adjusted that the side edges of theblank pass along the edges of said guides. The circumferentially-groovedpresser-rollers 7t press a gummed or moistened strip Vof paper againstthe edges of the blank, and said strip is pressed firmly 011 the top andbottom of the pasteboard blank by the action of the presser-rolls b,thus forming an edge binding. To paste on the angle binding-strips V atthe same time, the holders C are adjusted according to the requiredpositions of said strips. The anglestrips are pasted on at the same timewith the edge strips, and said strips can be pasted on throughout theentire width or only along the edges of the strips, thereby forming thehollow ridge W between the pasted edges.

It is evident that the strips secured on the sheet in one operation allrun in the same direction, and the strips running in a transversedirection must be secured by a second like operation.

The corners F of the blank may be cutout, as shown in dotted lines inFig. 7, so that the blank can be converted without any further cuttingor trimming into a box.

As the disks 6 serve as guides for the strips pressed down by therollers a, said disks must be mounted to yield.

Having thus described myinvention, Iclaini as new and desire to secureby Letters Patent The method herein shown and described of providingpasteboard blanks for making pasteboard boxes with angle binding-strips,consisting in grooving the pasteboard blank on the outside, thengrooving or crimpingthe binding-strips longitudinally, and pasting theside parts of said strips on the blank at the sides of the grooves, theblank being flat while the strips are being pasted on, substantially asset forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

TIIEODOR REMUS.
